There is a limit to what can be seen with visible light. Light has a wavelength (length), and those shorter than the wavelength of light can not be seen by the eye. There are limits of optical microscope / microscope there.

Therefore, an electron microscope using an electron beam (electron beam) whose wavelength is shorter than visible light.


In the past, there were only 10 million yen or more for digital micrometer microscope. Right now, some digital micrometer were about 6 million yen.


In various regions, there are public industrial testing laboratories, some of which offer testing services and equipment usage with electronic microscopes.


※Please note that we do not handle electron microscopes.
